SEAL-LOCK.-

SPECIFICATION forming part of Letters Patent No. 295,514, dated March 25, 1884.

Application filed November. 3, 1883. (No model.)

To all whom it may concern:

Be it known that 1, ANDREW B. BARNARD, a citizen of the United States, residing in St. Joseph, in thecounty of Buchanan and State of Missouri, haveinvente d a new and useful Improvement in Looks for FreightOar Doors, of which thefollowing is a specification.

This invention relates to the construction of that class of locks for freight-car doors con sisting, essentially, of a bolt passing through the door into the wall of the ear, or into the door opening, so as to engage with the doorpost.

My object in the invention has been to render the bolt secure when in the locking position, and to simplify the deviceand its operation; and it consists in the novel construction and combinations of parts hereinafter set forth.

In the accompanying drawings, Figure l is a horizontal section of the door and adjacent partof the wall of a freight-car, showing the door open and unlocked. Fig. 2 is a similar view, with the door closed and locked. Fig. 3 is a horizontal longitudinal section of my improved lock, the bolt being in position ready for withdrawal in unlocking, or at the instant of insertion inlocking. Figs. 4and 5 aretransverse vertical seetionsupon the line mm of Fig. 3, the first showing the boltlocked and the second showing it in the same position as in Fig. 3. Fig. 6 is a front view of the invention; and Fig. 7 is a side view of the same.

In the drawings, A represents the door-opening; A A thedoor-posts, and A thedoor of an ordinary freightcar. N ear the side edge of the door my improved lock is applied; and

it consists of a barrel, 13, adapted to be inserted in the door, and to pass from the outside to the inside thereof, and of uniform diameter, except at its outer end, b, where it is made smaller to conform to and afford a bearing for the shaft or central portion, a, of the bolt 0, which slides and oscillates in said barrel, and also to form a shoulder which will engage with the feather I), to permit the'passage of the feather 0. The

inner end, 0 corresponds in diameter to the main bore of the barrel, thereby affording the bolt a close bearing at that end. At its outer end the bolt carries a projection in the form of an eye, 0, by means whereof it maybe turned in the barrel and pushed into or pulled out of locking engagement. The major part of said eye lies at one side of theaxisof the bolt, and aids as a weight in its oscillation. Surrounding and formed upon the barrel at the outer end is the face-plate or disk D, and upon this disk is cast the outstanding vertical eye or loop d. This loop is so located that when the bolt is pushed in to lock the door the eye 0 will lie adjacent to it; and the bolt may then be secured by passing the hasp of a padlock through said loop and eye, or by passing a sheet metal or wire seal through them in a similar manner. An instance of this use of a sheet-metal seal, G, the ends whereof are eyeleted together at g, is illustrated in the drawings; and, as it is a matter of very great convenience to the trainmen that these seals, which serve also as designation-tags, should beso attached that they may be read without being handled and positioned every time they are inspected, I pro-, vide the outer edges of the loop d, or of the eye 0, or the outer edges of both, with shoulders f f, which will sustain the seal in a horizontal position parallel to the car side, as illustrated in Fig. 6. The initials of the road and the number of the station to which the car is destined may be stamped upon the metal of the seal, and thus rendered plainly visible.

hen the barrel and face-plate are made in two parts, as: iuthe drawings, the dividing-line being indicated by m, I provide one of the parts with A projections 91. upon one of the abutting faces registering with V-cavities in the other part, so that when inserted snugly in the door, and one of said parts is fastened ,to the door, as by the rivet 0, the entire device is incapable of removal without destruction of the rivet. riveted or screwed when this construction is adopted. These projections and cavities also insure accuracy of position when the parts are assembled. I l

The other part may or may not be lel to the bolt-eye; though I prefer to make it standing loop, d, lying vertically parallel to upon the plate. said eye, said eye or loop, or one of them, be-
